Polk SurroundBar 9000 IHT Soundbar HT Labs Measures
This graph shows the quasi-anechoic (corrected for on-wall boundary gain and employing close-miking of all woofers) frequency response of the SurroundBar 9000 IHT soundbar (purple trace) and subwoofer (blue trace). The left channel was measured with grille at a distance of 1 meter.
The SurroundBar 9000’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures + 4.11 /– 5.03 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 122 Hz, and the –6-dB point is at 106 Hz.
The subwoofer’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 38 Hz and the –6-dB point is at 35 Hz. The upper –3-dB point is at 100 Hz.—MJP
